Specification of Letters Patent.

Patented Feb. 15, 1916.

Application filed February 18, 1915. Serial No.8,977.

ington, have invented certain new and useful Improvements in Laundry-Mangles, of which the following is a specification.

This invention relates to steam-heated laundry mangles, and its object is the perfecting of machines of this class to render the same more efficient and convenient to operate and by which the ironing and polishing of the work is improved.

The invention consists in the novel construction, adaptation and arrangement of parts,as will be hereinafter described and claimed.

My improvements are illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the machine, shown somewhat diagrammatically, with an end-member of the frame omitted. Fig. 2 is a'vertical sectional view taken through the end of a cylinder and a steam superheater. Fig. 3 is a detail plan view to illustrate the change-speed driving devices of the machine. Fig. 4 is a front elevation of certain parts shown in Fig. 3. Fig. 5 is a front elevational view of the clutch controlling devices for the machine drivingmechanism.

The reference numerals 10 and 10 represent the cylinders of the machine and are arranged to have the axis of the former in a higher planeand in front of the other cylinder 10 These cylinders are provided at their ends with axle members 11 which are journaledin bearings provided in the end members, such as 12, of the machine frame.

As shown in Fig. 2, a pipe 13 makes communication through an axle 11 and between the interior of a cylinder and the coil 14 which, in turn, is connected by a pipe 15 with a steam generator, not shown.

The coil 14 is inclosed in a casing 16 and constitutes with a suitable fuel burner 17, a 'superheater whereby the steamat a relatively high temperature is supphed to the respective cylinders to render the same hotter than customary in mangles.

18 represents the receiving end of a siphon draw-01f pipe extending from near the bottom of a cylinder and through a pipe 13, as shown. On one of the axle members 11 of cylinder-10 is aspur-gear 19 in mesh with a s mllar gear 20 on an axle member of the cylinder 10}. The gear 20 is' also in mesh with a pinion 21 on a transverse shaft 22 carrying a spur-gear 22 which, in turn, 1s driven by a pinion 23 on a'transverse shaft 24.

An endless apron 25 passes about guide rollers 26, 27, 28 and 29, thence about a driving roller 30 in proximity to the firstnamed roller to which the apron returns after passing around approximately the entlre circumference of the cylinder '10; a second endless apron 32 passing around guide-rollers 33, 34 and 35 to and about a driving roller 36, thence about the guide roller 29 to a guide roller 37 in proximity to the guide roller 33, and. finally about nearly the entire circumference of the cylinder 10 to the roller 33. The driving rollers 30 and 36 have provided on their axles spur gears 30 and 36 of equal diameters, which intermesh with each other and are rotated by the gear 19 engaging the gear 30 The diameters of the gear-wheels 19 to 30 in relation to the diameters of the cylinder 10 and the rollers 30 and 36, are such that the peripheral speeds of the rollers are slightly less than those of the cylinders,

resulting in the aprons being driven at a lower velocity than the respective cylinders when passing about the latter. Provision is made for taking up any slack upon either of the aprons, as by supporting the roller 29 upon levers, as 37, pivoted at 37 to the machine frame and carrying a weight-37 at its free end.

Take-up screw devices, as 38, connected to slidable journal boxes 38 for other of the rollers may also be employed supplemental to the aforesaid weighted lever supports for the roller 29. The guide-roller 26 is mount ed in a frame 39 which is hingedly connected at 39 to the machine frame to enable the roller being swung up, as indicated by broken lines 26 At the front of the machine is a feeding conveyer comprising endless ribbons 40, so called which pass around a roller 41 and the nose 42 of a frame 43. This frame is hingedly connected to a support, such as the shaft of the roller 41, and is arranged to be swung up into dotted line position 43 Any suitable power transmission devices may be used to drive the feed ribbons 40,

such as a chain 44 passing about sprocketwheels mounted on the shafts of the rollers 41 and 36 and receiving motion from the latter.

45, 45 and 45 represent concave blades located as shown in Fig. 1, and serving as guides for the work as the same progressively travels about the cylinders.

The course of travel of the article in its passage through the machine is indicated by arrows in Fig. l and may be traced as follows: The operator spreads an article which is to be ironed and polished'upon the ribbon conveyer to be carried thereby under the guide roller 26 and between the apron 25 and the cylinder 10. The article thus engaged is carried around with the cylinder until it reaches the guide which causes the article to pass about the roller and into the interstice between the aprons 25 and 32, whereupon the two aprons serve to carry the article therebetween about the roller 29 to the roller 37 whereat the article passes over the roller 37 to be influenced by the guide 45 which leads the article -with the apron 32 against the periphery of cylinder 10 and thus continues to travel about this cylinder until guide 45 is reached which effects the passing of the article upon apron 32 about the roller 33 and is finally delivered over the roller 34 on a bracket table 46. An article in its travel through the machine, and while held successively in juxtaposition with. the cylinders, will be subjected to the high temperature at which the cylinders are maintained through the agency of the superheated steam. By thus operating'the cylinders under such a heat the aprons will exercise sufficientpressure against the goods to insure an efi'ective ironing action to the goods and will obviate any necessity of employing presser-rollers therefor, as have hitherto been utilized. Such resser-rollers require a covering of felt or an equivalent which are not only expensive but require more or less attention to keep in order. As before mentioned, the aprons travel at a slower speed than the cylinders, resulting in cylinders having a relatively faster movement than the goods to impart a polishing effect thereto.

The driving of the movable parts of the machine is attained by the followingdescribed appliances: The shaft 24 upon which the aforesaid pinion 23 is mounted, is provided with a spline 47 which engages in the hub 48 of a friction-wheel 48 to re ceive axial movement from the latter. 49 represents a forked arm carried by a rocker shaft 49 and'engaging a ring 51 seated in an annular groove provided in the hub 48.

Said rocker-shaft extends a short distance in front of the machine frame and is pro vided with an arm 50 which is connected by a rod 50 with an arm 52 of an oscillatory pedal device with branches 52, Figs. 3 and 4, whereby the forked arm 49 may be swung in one direction or the other to ad justably move the friction wheel 48 on its shaft. Complementary to said friction wheel is a friction disk 53 mounted on the end of a longitudinally disposed shaft 54 journaled in bearing boxes 55 and 55 56 represents a pulley to receive an endless belt (not shown) whereby the shaft 54 and friction disk 53 are rotated. Interposed between the pulley 56 and the box 55 is a helical compression spring 57 which tends to yieldingly hold'the disk 53 out of engagement with the friction wheel 48 58 is a thrust-screw which extends through a nut 59 fixedly secured to the box 55 and which has an end impinging against the shaft 54. The screw 58 is provided with an operating handle 60 for advancing the screw to cause said disk to be moved into engagement with the friction wheel 48 or for retracting the screw to allow the spring 57 to separate the friction members and render the machine inoperative.

61 represents a I torsional spiral spring having its ends connected with the handle 60 and the nut 59 and serving to rotate the screw in a direction to withdraw the disk from the friction wheel. The screw is, however, releasably held in its operativeposition. by a spring-pressed dog 62 having a hook which engages a stud 63 provided on the screw handle. Supplemental to said handle is provided an emergency stopping device within convenient reach of the operator employed in supplying articles to the ribbons 40. Such means comprises a plate 64 hingedly connected to links 65 which are themselves pivotally connected by pins 66 to the machine frame.

Rigidly connected to one of the pivotal pins of the plate is an arm 67 which, as best shown in Fig. 5, is connected by a rod 68 with the dog 62 so that by pulling the upper or free end of the plate the dog is disengaged from the handle, whereupon the spring 61 asserts itself to disengage the friction members with a consequent stopping of the machine. The purpose of supporting the plate 64 and its attachments by the links 65 is to enable the same to be swung upwardly to give access to the cylinder 10 after the roller 26 and the ribbon frame 43 have been tilted up, as before explained.

The cylinders and aprons are operable in opposite directions, selectively, by shifting the friction wheel 48* to one side or the other of the axis of the disk 53 by depressing one of the pedal arms 52.

The invention will, it is thought, be understood from the foregoing description.

What I claim is 1. In a mangle, the combination with the machine frame, two cylinders journaled therein and arranged one in advance of the other and at a higher elevation than the rear cylinder, endless aprons for the respective cylinders, the apron for theforward cylinder being arranged to feed to and remove the work from such cylinder at the forward side thereof and the other belt is arranged to feed the work to and remove the same from the rearmost cylinder at the upper side thereof, whereby the Work is caused to traverse almost the entire peripheries of the cylinders in its travel through the machine.

2. In a mangle, the combination with the machine frame, a pair of steam-heated cylinders journaled therein, endless aprons for the respective cylinders, and driving and guide rollers for carrying and directing the aprons, of power transmission mechanism for driving the cylinders and aprons at selected speeds and in different directions, said mechanism comprising toothed gear wheels operatively connecting said cylinders and driving rollers, a shaft operatively connected with said gears, a friction membersplined to said shaft, means to regulate the position of said friction member axially of the shaft, a

second friction member, a spring tending to retain said second member out of engage- 3. In a mangle, the combination with the machine frame, cylinders journaled therein,

a ribbon conveyer hingedly connected to the frame in front of one of said rollers, endless aprons for the respective drums and extending into proximity to said conveyer, guide and power-driven rollers for the aprons, and means hingedly connected to the frame for supporting the guide-roller for one of the aprons, said means being adapted to hold the respective roller in operative position in" relation to the adjacent cylinder and the conveyer or to be tilted up to give access to the referred to cylinder and permit the tilting up of the conveyer.
